2S 15A 7.4V NMC Battery Protection Board BMS Module

The 2S 7.4V 15A NMC Battery Protection BMS Module is a compact and reliable circuit designed for 2-cell lithium battery packs. It provides safe charging and discharging with built-in protection against overcharge, over-discharge, overcurrent, and short circuits. Ideal for robotics, DIY power banks, and energy storage systems, ensuring efficient performance and extended battery life.

Features:

1. Battery Configuration: Supports 2S (7.4V nominal, 3.7V per cell) Li-ion/NMC battery packs.
   
2. Overcharge Protection: Prevents battery damage by stopping charging when voltage exceeds limits.
   
3. Over-discharge Protection: Cuts off discharge when voltage drops too low to maintain battery health.
   
4. Overcurrent & Short Circuit Protection: Detects high current faults and restores operation automatically once safe.
   
5. Cooling Support: Heatsink recommended for continuous 15A operation.
   
6. Effective Life: Designed for over 50,000 hours of reliable use.
